Create a ManagedDatum object having the same value as the specified original object. Optionally specify an allocator (e.g., the address of a bslma::Allocator object) used to supply memory; otherwise, the default allocator is used. This operation performs a clone of the underlying Datum, see {Value Semantics} for more detail.
